Application filed November 7, 1927. Serial No. 231,612.

This invention aims to provide a simple but efficient tool whereby thebattery terminal may be loosened, when it has become corroded on thepost of the battery, or when the clamping bolt in the battery terminalhas become corroded in its place.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of theinvention.

In the drawings Figure 1 shows in side elevation, a tool constructed inaccordance with the invention;

Figure 2 is a urel;

Figure 3 is a section on the line 3-3 of Figure 2, remote parts beingomitted, and the tool being shown in place in operative position on theterminal of a battery; and

Figured is an elevation showing one of the jaws.

The tool for loosening battery terminals, shown in this application,comprises levers 1 and 2 which are crossed upon each other as at 3, andconnected pivotally at their place of crossing, by a pivot, bolt, orother pivot element 4. The lever 1 has a jaw 5 and the lever 2 has a jaw6, the jaws: 5 and 6 cooperating in a way which will be describedhereinafter. The jaw 6 has a substantially fiat detail enlarged fromFig.

a surface 7. The jaw 6 has lateral grooves 8 and 9, which converge andintersect the flat surfage 7, to form an edge 10.

The groove 9 in Figure 3 is shown as receiving the end 11 of theclamping bolt 12 in a battery terminal 14 and the groove 8 is shown asreceiving one corner 15 of the nut 16 on the bolt 12. The grooves 8 and9 are of like construction, to provide for a reversal of the tool; thatis, if the bolt 12 happens to be turned end for end from the position ofFigure 3 it may be expedient to receive the end 11 of the clamping bolt12 in the groove 8, and to receive the corner 15 of the nut 16 in thegroove 9, the jaw 5 then engaging the arm 21. The jaw 5 has a chiseledge 17 for acquiring a hold on the inclined surface 18 of one arm 19 ofthe battery terminal 1 1. In the event that the nut 16 happens to be ofsuch shape, or happens to be turned into such a position, that thecorner 15 is not received in the groove 8, then the flat surface 7 ofthe jaw 6 may bear against the nut. When the jaws 5 and 6 are movedtoward each other, after the nut 16 has been backed off a little, asshown in Figure 3, the arm 19 will be moved lengthwise of the bolt 12,thus spreading the arms 19 and 21 apart. This loosens the terminal fromthe post 20, but the bolt 12 remains stuck in the arm 21. It is a goodplan to leave the bolt 12 stuck in the arm 21 because then the bolt willnot rotate when the nut 16 is turned up tight again, and a person doesnot have to hold the bolt with a wrench. The edge '10 is adapted to bereceived in the angle between the end 11 of the clamping bolt 12 and theouter surface of the nut 16, as shown in Fig ure 3.

What is claimed is A tool for loosening battery terminals, comprisingpivotally connected levers provided with cooperating jaws, one jawhaving a, substantially flat surface, and having grooves which convergeand intersect said surface, one groove being adapted for the receptionof the end of the clamping bolt in a battery terminal, the other groovebeing adapted for the reception of one corner of the nut on the bolt,the grooves being of like construction to provide for a reversal of thetool, the other jaw having a chisel edge for acquiring a hold on theinclined surface of one arm of a battery terminal.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature.
